and that other operating connections than those shown at 9 and 10 may beemployed.

A sprocket chain or other connection 11 passes around the wheels 3around another wheel 12. In order that the invention may be adapted forhand steering, as for instance on vehicles which have no self-containedpropelling power, the wheel 12 is preferably carried by the stem 13which has a hand steering wheel 14 which may be grasped by the occupantof the' drivers seat 15. y

At 16 there is a shaft which may be driven by power in any preferredmanner,l as for instance, by the motor, shown diagrammatically at 17,that is used to propel the vehicle, said shaft carrying gears 18 an 19which, respectively mesh with gears 2() and 21 on shafts ings permittingtheir forward ends to rise and fall. The shafts Z2 and 23 carry frictionor other wheels 24 and 25 which, respectively, are adapted to bearagainst the lower faces of the wheels 3 and 4.

There are two spring actuated pedals or foot levers .26 and 27,respectively, connected to the shafts 22 and 23 by the rods 28 and 29.Normally the springs hold the pedal levers 26 raised and the wheels 24and 25 out of engagement with the wheels and 4. If it is desired to turnthe vehicle in one direction or the other, the driver depresses eitherthe lever 26 or lever 27, thereupon throwing the given friction wheel 24or 25 against wheel 3 or wheel 4, and rotating said wheels so that theground steering wheel 2 will vbe turned in the desired direction,thereby utilizing power to steer the vehicle. The power and handsteering mechanisms may be used separately or together.

Having thus described my invention, I claim as new and desire to secureby ters Patent, is 1 ln a steering gear for vehicles, the combinationwith ground steering wheels, of independent wheels having an operativeconnection with each other, operative connections between the respectiveindependent wheels and the respective ground wheels, whereby all of saidwheels will turn in unison, bodily To all whom 'it may concern:

Be it known that l, JAMES M. GiLsTRAr, a citizen of the United States,residing a Fresno, county of Fresno, and State of California, haveinvented certain new and useful lmprovements in Steeringear for Vehiclesof All Kinds, of which the following` is a specification.

This invention relates to steering gear for vehicles of all kinds.

The present invention has for its objects the provision of a novelsteering gear adapted for use on either horse or motor propelledvehicles of all kinds and constructed and adapted for steering by handor by power, and to this end the invention consists, in one aspect, ofcooperatively related wheels operative connections with the wheels ofthe vehicle and associated with a hand steering wheel, and in anotheraspect, of coperatively related wheels operatively connected to theground steering wheels of the vehicle and power driven means havingcontrolling devices, whereby, ding to manipulation, the ground steeringwheels of the vehicle will be turned in one direction or the other bythe utilization of power derived from the propelling agency of thevehicle, or other source.

The invention is set forth fully hereinafter and the novel features arerecited in the appended claim.

ln the accompanying drawings z-Figure 1 is a bottom view with thevehicle body in section; and 2, a side elevation with the body insection.

The vehicle 1 is provided with ground steering wheels 2 of the usualpivoted arrangement. Mounted in suitable bearings on the vehicle 1 aresprocket or other wheels 3 and 4, which are, respectively provided withsmaller sprocket or other wheels 5 and 6, in turn operatively connectedto arms 7 and 8 of the brackets which carry the wheels 2, theseconnections in the present instance being sprocket chains 9 and 1() runaround the sprocket wheels 5 and 6, respectively. lt will be understoodthat the wheels 3, 4, 5 and 6 are not necessarily sprocket wheels whatLet and 4 and alsoY 22 and 23 mounted in bearv shiftable power-operatedshafts, wheels card ried by the respective shafts adapted, respectively7 to engage the independent wheels aforesaid, and pivoted leversrespectively operatively connected to the respective power-operatedshafts aforesaid, whereby either of the power driven wheels may beengaged with one of the independent wheels aforesaid, sii-id drivingwheels being adapted to turn in opposite directions.
